Microwave and dishwasher safe, because coffee cups shouldn’t be high maintenance. Wash gently and skip the abrasive cleaners and steel wool. Avoid sudden temperature changes, cold liquids in hot glass, and aggressively dropping in ice. The outside may play it cool while your coffee absolutely does not, so sip accordingly. Maximum temperature differential: 248°F (120°C). Slight variations in size and shape are part of the glass-making process.

Kinto is the Japanese brand making everyday rituals feel like little luxuries. From pour-over coffee gear to glassware and travel bottles, they’ve mastered the art of slowing down—designs that are simple, thoughtful, and just a little bit indulgent. Minimal, functional, and quietly irresistible: proof that even your morning brew deserves good design. At Hei-Day, the founder’s Kinto teapot is on daily duty—and her water bottle is practically a travel sidekick.
